ATTACHMENT FOR SOIL-PIPES.

SPECIFICATION forming part of Letters Patent No. 743,269, dated November 3, 1903,

Application filed October 16, 1902. Serial No. 127,460. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH ALEXANDRE GODIN, a subject of the King of Great Britain,

residing at St. Johns, county of St. Johns,

Province of- Quebec, Canada, have invented certain new and useful Improvements in Attachments for Soil-Pipes; and I do hereby declare that the following is a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a device to be attached to or inserted in soil and other drain pipes and the like to allow the ready inspection and, when necessary, cleaning thereof without the necessity of taking apart the pipe should it become obstructed or of fishing through the same, asfrequently is necessary with the present system; from the open end thereof and around traps and bends, which makes the work both difficult, tedious, and nncleanly.

An essential feature of my invention consists in an opening in the'side of the pipe, which is closed by a cover, and the latter is made readily removable, whereby the inside of which is made of metal, such as cast-iron or other solid material, and is provided with ahermetic joint, which avoids the risk of accident by not only protecting said glass against fracture from without, but also forestalling the possibility of leakage or escape of the contents of the soil or drain pipe in case the glass should become broken by excessive pressure.

Still another feature of my improvement consists in the peculiar form of doors, both of which are provided with slotted extremities at each end, the slot in one end being open and the door being held when closed by a pair of bolts passing through each slot and the slots being so arranged that when the bolts are loosened,whioh may be accomplished with either door separately by means of separate nuts clamping each door, the door may be readily slid back, so as to release the bolt from the open slot and allow the door to turn edgewise around the bolt passing through the closed slot thereof as a hinge.

My invention consists,further, in the peculiar construction and combination of parts,

which will be set forth in the accompanying description and particularly pointed out in the claims. 7

I have shown the most approved form of my attachment in the accompanying draw ings, wherein- Figure 1 is aface view of a joint of pipe provided with my attachment. Fig.2 is a central longitudinal section thereof. at right angles to Fig. 1, and Fig. 3 is a transverse section centrally through the attachment in a plane at right angles to Fig. 2.

4 is a short joint or length of pipe having at one end a bell 5 and at the opposite end a spigot-bead 6 of the ordinary pattern and formed thus to be inserted as a part of the length of the drain-pipe to which it is to be attached. This joint or length of pipe is made of cast-iron ordinarily and will be inserted at intervals of several feet or yards in the pipe, according as may be desired. From a point in the length between the bell and spigot thereof there arises a transverse T or branch 7, which is open at its 0* t er end and provided with an annular reinforcement 8, which is provided around its inner edge with a rabbeted groove 9, adapted to form a seat for a disk of strong plate-glass 10, which is of the same diameter as the outer edge of said groove. This disk of glass is confined in its position by a clamping-ring 11, which is internally rabbeted, as shown at 11*, and provided at opposite extremities of a diameter with a pair of slotted cars 12 and 13, the ear 2 at one side having an open slot 14 therein, while the opposite ear 13 is provided with a closed slot 15. The reinforcement 8 of the branch is likewise provided with a corresponding pair of ears 16, cast integral therewith, and through each of which passes a bolt 17, whose'head is seated on the lower side'of said ear 16, and the clamping ring 11 is clamped in place by a pair of nuts 18, carried by each bolt and seated on the upper side of the slots 14 and 15. p

' In order to provide a hermetic joint or seal between the glass plate and the branch and likewise between the branch and the clamping-ring, I provide gaskets 19 and 20, respectively located above and below said glass plate and between the plate and the end 8 of the branch and between the plate and the clamping-ring, these gaskets being made of resilient material-such as leather, rubber, or similar packin'g-whereby the tightening up of the nuts 18 will cause the clamping-ring to tightly grip the plate and prevent the same from being moved from position, as well as from being broken by any slight jar or pressure. transparent inspection aperture through which the contents and condition of the pipe may be viewed, and by passing from one to anotheralong the length of pipe the point of obstruction may be readilylocated, and thereupon the pipe may be opened at the proper point by simply sliding back the clampingring 11 upon the slotted ears 12 and 13 until the ear 12 is disengaged from the bolt 17, whereupon said ring may be turned to release the glass plate, and the latter removed and access to the interior of the pipe can be had, and upon closure of the pipe the reverse operation is carried out, as will be readily understood, and this can be done in a few minutes.

In order to protect the glass plate against possible breakage either from without or by excessive pressure from within the pipe or which might be caused by any defect, such as a crack in the glass, I provide, further, a closure plate or door 21, which is in the form of a disk or so-called blank flange provided with a pair of opposite ears 22 and 23, and thus being of the same exterior form as the ring 11, and this, like the other metallic parts of my device, will be ordinarily made of castiron, although I do not of course confine myself to the use of that material. The ears 22 and 23 are slotted, as shown at 24 and 25, in the same manner as the ears 12 and 13, and the bolts 17 are prolonged to pass through these ears and provided with secondary nuts 26 to clamp the said door thereon, so that upon releasing said nuts the plate 21 may be slid back and disengaged from the bolt 17, passing through the open slot 25 in the same manner as the clamping-ring 11. Immediately under the plate 21 and between it and the clamping-ring 11 I place a packing disk or gasket 27, of leather, rubber, or other suitable material, said gasket being adapted to form a hermetic joint between the ring and the plate and to form a tight closure for the opening.

In many casesas, for instance, where the pipe is placed in upright position-it will be advantageous to form the upper side of the branch 7 at a slight angle to the length of The glass plate 10 thus provides a the pipe in order to facilitate inspection from above or in a downward direction into the pipe, as shown in Fig. 2 of the drawings.

The advantages of my improvement will be obvious from the foregoing description and do not require further explanation.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make such modifications as are included in the scope of the following claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
